本文是纤维增强塑料冲击性能研究的首篇,先从简支梁冲击,应用复合材料的强度准则和能量法则推导出冲击韧性与材料性能—尺寸及损伤区的关系。
This paper is the first one to study the impact properties of fiber-reinforced plastics. The relationship between impact toughness and material properties-size and damage area is derived from the simply supported beam impact, the strength criterion and the energy law of composite materials.
